I would second pastrychef's opinion that the WiFi card or PCIe adapter may be defective.

Alternatively one or the other is not installed correctly, in the PCIe slot or on the adapter card.

The Card is definitely not showing up in the PCIe Device list.

Bluetooth working, but wifi in same card is not working
  1. Description of WiFi/Bluetooth problem:
    I had Catalina running with everything more or less functional, but wanted to optimize my build so I did a clean install of latest OC with Big Sur. I have a BCM94360CS2, which was running in M2 slot previously, but I moved it to PCIe x1 because I use internal graphics and was having heat issues due to location of M2. Bluetooth still fully operational (USB mapped correctly), but wifi is not working at all. OS acts like it's looking for networks but can't toggle wifi on/off or add a network (I get the following error). I removed the unsupported injector from the Airport Broadcom fixup kext, but no dice.

Try disabling CFG lock in BIOS and this config.plist.

I don’t see the option in my bios. Will the config.plist suffice? I see two options, should they both be disabled?

The guide I followed said to enable the xpcmcfglock if you don’t see cfg lock in bios.

That will work, but the latest Z390 BIOS from Gigabyte should have the option to disable it... Doing it in BIOS is preferable.

I have the itx version of the board, which has its own bios releases. Of the two cfg entries in the screen I shared, which ones should be enabled or disabled?

@pastrychef I had to use these instructions to set CFG Lock to 0, which I've done, and also set the two cfg entries to "false" in the config.plist. Still don't have any wifi connectivity though.

Is the Wi-Fi appearing and just not functioning?

Please try going to Library/Preferences/SystemConfiguration/ and delete the following:
com.apple.airport.preferences.plist
NetworkInterfaces.plist
preferences.plist

Then reboot.

Ok. just did that and now WiFi doesn't appear in Network Preferences at all. Not sure where to go from there. How can I tell if the pcie is picking up the wifi? Bluetooth in the same card is working, but I think that's because it's via USB.

Try launching Hackintool and look in the PCI tab.

Also, does the Wi-Fi appear in Windows or Linux?
